ADJUSTABLE HOUSING FOR GOVERNORS.

Application: filed May 13,

throttling governors. are either dri ven by the varioi1s-moton shafts or offthe tan belt. Driving the governors directly fIEODhhhB GIb gine requires additional expense 01% added gearing; shafitsand the like,, which a-re all subjectv to Wear and; require continual l lubrication, It is. thereforma; recognizect'fact that the: simplest and. least exp nsive method oif driving a governor is fiuQm the fan. belt.

However, this method developsicertaing objections, dlue toithefactthat; it requi es proper alining of three pulleys with the fan belt,

namely-, the drive pul:1ey; fan pulley,,. and

governornpulley; Shouldpany of these be;

slightly out oat alinement, the belt. is caused to climb, which results in; undue wear upon the same, or jumping: of the belt :firom; the

pulley. In. an. endeavor: tor overcome theseobjections attempts havebeen made to incorporate a. governor directly in-theftan; pulley, but these have not, been. ,suec ssfiul, j

dueto. the fact: that it is; impossible toincrease the size of the fan pulley; sufliciently to permit. a practical'i Struc ure,- Of g r o to be housed thereint.

It is; therefore theiprimary object of the present inventlon. to overcome the foregoing objections and: difficulties. by the provision ot a simple, compact and eflicient throttling governor combined with the; fan belt pulley.

A furtheryobject resides, the; method of attaching the governor whereby the pulley may be adjusted in various directions to insure a tight belt and; proper tracking of the same.

A more specific object resides;. in the adjustable attachment Off the throttling, governor with the elbow connection; between, the wa ter'jacket of the motor and; the radiator, whereby the governor is combinediwiththe fan belt pulleyin theconfined space; between the engine and the radiator,

With the above. and other ohjeets in; View,

.whichwill appean asuthe description proseeds, the invention resides in the novel'con struction, combination anfili arrangement of parts substantially as hereinafter described.

and more particularly definedby the apeiaims it; being understood th at, such.

changes. in the precise embodiment. 0t

herein disclosed; invention may be made as come within the scope of the claims,

In the accompanying drawing is. illustrated; one complete example of, the physical embodiment of the present invention. constructed according to; the best mode so iiar devised for the; practicalapplication of the principles thereof.

F'g-u-re lis a front ele V ,ational view illustrating a throttling governor constructed, in accordancewith the present invention, and the methodi oi attaching the same to a portiomof theengine Figure 2. is a side elevationof thesame.

Figure is: a detailed sectional viewtaken on the line 37-3, of Figure 1.

;I-n,con;vent1,onal; structures; of tractors and power. units now uponthe market, it} is highly desirable that the. same be. as compact V as possible. Consequently, the. space between the. motor and; radiator is confine to a minimum, which renders it; driificult to position a governor b tween the, fan, and

moton, To overcome this it'is proposed/to attach the governor directly to' theelbow connection, which, in conventional structures; is. provided between. the water jacket oia. motor and the'radiator, For th foregoing; purpose. the conventional elbovv is replaced by the elbowl otspecial: construe tion, which is provided, with a pair of: oppositely disposed" lugs 2 tor the reception of bolts 3 tha-t carry a, U.s ha-pe d. bracket 4. Depending f om: e l o is a. bo s 5; receiyinggth e t 6,. Whie t-passes through] the horiiontai, slots 7 provided in the a rms. of

thebracket 4'. Bye this, arrangement it, will be readily seen that thebracket. 4, WhiQlI iS pivot-ally carried upon the bolts, 8, may. be

pivotal-1y adjustedr and securely; looked in adjnsted, position by drawing up. Q11 the therein, which shaft serves to. carry a. conventional, .structnre; oi goyernor mechanism 10, the same serving to' rock the arm 11,

which arm; is connected to the, throttling valveilever l2jhymeans ofii the linklB; The

nism. In the customary impeller.

with a boss 23 adapted to receive an impeller shaft, the boss being normally closed by Consequently, it is thought unnecessary to go into a detailed explanation of the same at thistime.

Formed integral with the housing 8 are a pair of oppositely disposed bearing blocks 14, which are provided with longitudinal grooves 15 for the reception of the arms of the bracket 4. By this arrangement the housing 8 is confined in the bracket and slidably carried thereby for vertical adjustment. A set screw 16 threaded through the lower portion of the bracket at and provided with a lock nut 17 engages a boss 18 provided on the bottom of the housing 8 and serves to raise or lower the housing to the desired position.

Pinned or otherwise suitably secured to the shaft 9 is a belt pulley 19 provided in its face with a plurality of tapped openings 20 to permit attachment to the fan blades 21. Thus it will be seen that the pulley 19 serves two functions, namely, to carry the fanblades and drive the governor mechaarrangement the belt drive pulley is usual y mounted directly upon the crank shaft of the motor and is therefore positioned in alinement withthe fan pulle below the same. It will therefore be seen t at in order to tighten the belt the housing 8 and pulley 19 must be adjusted upwardly by means of the set screw'16. In its adjusted position the housing 8 is locked in the bracket 4 by means of a transverse bolt 22 passing through the arms and adapted to contract the same sufficiently to cause them to securely engage the bearing blocks 14, there being a certain degree of resiliency in the arms 4.

In some instances it may be desired to rovide the elbow 1 with a water circulating The elbow is therefore provided means of the threaded plug 24. when the .impeller is not used.

From the fore oing description, taken in connection with t e drawings, it will be seen that a very simple, compact and eflicient structure has been provided, which readily combines a governor with the fan pulley, thereby eliminating the difiiculties heretofore encountered in other types of governors. It will also be seen that the pulley 19 can be readily adjusted vertically to insure a tight belt, and through the horizontal adjustment of the bracket 4 the pulley may be easily alined with the driving .belt to eliminate climbing of the belt upon the pulley and insure proper tracking of the same.

A throttling governor housing assembly for internal combustion engines comprising,- a U-shaped bracket attached to and straddling a portionof the engine for horizontal adjustment, a housing verticall adjustable in said bracket, governor mec anism conmech tained within said housing, and a pulley for driving said governor mechanism.
